To find the approximate diagonal through the cylinder, we can use the Pythagorean Theorem.
The diagonal can be thought of as the hypotenuse of a right triangle, with the radius of the cylinder as one leg and the height of the cylinder as the other leg.
By Pythagorean Theorem, the diagonal (D) can be calculated as:
D^2 = radius^2 + height^2
D^2 = 7^2 + 12^2
D^2 = 49 + 144
D^2 = 193
Taking the square root of 193, we get:
D = √193
D ≈ 13.89 inches
Therefore, the approximate diagonal through the cylinder would be approximately 13.89 inches.
